PASSENGER BUS ALERT SYSTEM FOR EASY
NAVIGATION OF BLIND
ABSTRACT:
Talking signs, guide cane, echolocations are all useful in navigating the visually
challenged people to reach their destination, but the main objective is not reached that it fails
to join them with traffic. In this project we propose a bus system using wireless sensor
networks (WSNs). The blind people in the bus station are provided with a ZigBee unit which
is recognized by the ZigBee in the bus and the indication is made in the bus that the blind
people is present in the station. So the bus stops at the particular station. The desired bus that
the blind want to take is notified to him with the help of speech recognition systemHM2007.
The blind gives the input about the place he has to reach using microphones and the voice
recognition system recognizes it. The input is then analyzed by the microcontroller which
generates the bus numbers corresponding to the location provided by the blind. These bus
numbers are converted into audio output using the voice synthesizer APR 9600. The ZigBee
transceiver in the bus sends the bus number to the transceiver with the blind and the bus
number is announced to the blind through the headphones. The blind takes the right bus
parked in front of him and when the destination is reached it is announced by means of the
GPS-634R which is connected with the controller and voice synthesizer which produces the
audio output. This project is also aimed at helping the elder people for independent
navigation.
